The short-term effect of nitrogen on freshwater cyanobacteria and cyanotoxins

open access: yesFrontiers in Water
Toxic cyanobacterial blooms are a worldwide concern. Nutrients are among the numerous factors that trigger cyanobacterial blooms and the production of cyanotoxins. This study aimed to assess the effect of nitrogen on cyanobacteria and cyanotoxins through

Diversity and seasonality of cyanotoxins in Lake Garda (Italy): potential for hepatotoxic microcystins transfer through the food web [PDF]

open access: yes, 2012
42012 SHA 1openToxic cyanobacteria occurrence is a global concern in many eutrophic freshwater ecosystems due to their production of highly toxic secondary metabolites (cyanotoxins): hepatotoxins (microcystins, nodularins), neurotoxins (saxitoxins ...

Methods for rapid extraction of microcystin-LR and microcystin-RR

open access: yes浙江大学学报. 农业与生命科学版, 2005
Simple analysis methods using microwave and boiling waterbath to solve the problem for microcystin-LR (MCLR) and microcystin-RR (MCRR) extraction from cyanobacteria cells were studied as a substitute for the traditional solvent extraction methods. Standards were used to confirm the feasibility and efficiency of both methods.
